one. It is a vertical line of symmetry which splits the A in half.

Normally none but if it's an isosceles trapezoid it has one
A regular polygon with 22 sides has 22 lines of symmetry. Each line of symmetry passes through one vertex and the midpoint of the opposite side, or it can pass through the midpoints of two opposite sides. This property holds for all regular polygons, where the number of lines of symmetry is equal to the number of sides.

It has two lines of symmetry, one each perpendicular to each other passing thru the center of the rectangle

When you rotate a shape less than 360 degrees it will look the same. for example a square has rotational symmetry of 4 because it can be reotated 4 time (over 90 degrees) and it will look the same.
Rhinoceroses have like all vertebrates, have bilateral symmetry.
